(Generalized) eigenvalues for complex matrices #82

Closed MaxRang closed 6 months ago

MaxRang commented 6 months ago

Hi,

Thank you for creating this library! It will be very useful for me in my attempts at rewriting some old FORTRAN codes to Rust.

For my specific purpose, I need generalized eigenvalue solvers (i.e. dggev) and complex matrix eigenvalue solvers (zggev, zheev, zgeev). Are there currently plans to add these?

Thanks!

Hi, yes! these four functions (and more) are coming soon.

cpmech commented 6 months ago

These functions are now available (russell_lab version v0.9.0):

dggev -- wrapped by mat_gen_eigen
zggev -- wrapped by complex_mat_gen_eigen
zheev -- wrapped by complex_mat_eigen_herm
zgeev -- wrapped by complex_mat_eigen

Feel free to suggest more functions!

Thank you for the amazingly fast implementation!
